MINERS CARBID-LAMP.

Specification of Letters Patent.

Patented Dec. 27, 1921.

Application filed August 7, 1917, Serial No. 184,895. Renewed May 5, 1921. Serial No. 467,126.

1 0 all whom it may concern Be it known that I, IVIN I. BILLINGS, a citizen of the United States, residing at Marial, in the county of Curry, State of Oregon, have invented a new and useful Miners Carbid-Lamp; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved miners carbid lamp, and an object of the invention is to provide a simple, eificient and practical lamp which may be manufactured for a small cost and sold at a reasonable profit.

In the majority of lamps of this kind, the lamp or the light therefrom projects from the side of the holder, or laterally, and this has been found as a disadvantage, for, when the miner is at work, it is diflicult to hang or suspend the lamp so that its rays are directed on the work. An object of the present invention is to overcome this disadvantage by arranging the burner on the top of the lamp, so that the light will be distrib uted equally in every direction.

A further object of the invention is to provide a carbid receptacle or tank which is large enough to contain carbid suflicient to last four hours, which is equal to half a shift, and in all other lamps, this feature has been overlooked.

A further object of the invention is to provide a miners lamp that will fit any miners candlestick or holder and does not require a special stick, as in the case of other lamps.

A further object of the invention is the provision of a lamp having double gas passages intermediate the carbid receptacle and the burner, which double passages act as a storage tank and permits of an even flow of gas to the burner, which. are features overlooked in other lamps new in use.

A. further object of the invention is to provide an improved lamp having an elongated water space surrounding the double gas passages, thereby acting to cool the gas before it reaches the burner, hence, eliminating fluttering of the light, which is an exceedingly fault or disadvantage found in other lamps now in-use.

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in elevation of the improved lamp constructed in accordance with the invention.

Fig. 2 is a vertical sectional view.

Fig. 3 is a top plan view.

Fig. 4 is a sectional view on line 4- 1 of Fig. 1.

Referring more especially to the drawings, 1 designates the carbid receptacle of the lamp, and which may be any suitable size or shape,-and constructed of any suitable material, preferably sheet metal. The top of the receptacle has a flanges opening 2, the flange 3 of which is interiorly threaded, as shown at 4:, whereby the lower end of the elongated tubular casing 5 may be threaded in engagement with the flange. The elongated tubular casing 5 has a bottom 6 provided with an annular flange 7, which is exteriorly threaded and threaded into engagement with the inner wall of the casing .55. The top 8 of the casing has a flange 9 which fits and is brazed or otherwise connected on to the casing 5. The bottom 6 of the casing has an additional annular flange 10 provided with interior threads 11. A casing 12 provided with passages 13 is arranged within the casing 5 and spaced therefrom. To form the passages 13, a partition wall 14, as shown in Figs. 2 and 1, is provided. The opposite ends of the wall 14 have disk walls 15 and 16. The upper disk wall 15 is brazed or otherwise connected to the wall 14 and to the cylindrical wall of the casing 12, as shown at 17 and 18 respectively. The lower disk wall 16 is likewise connected to the partition wall 14 and the wall of the casing 12, respectively, as shown at 19 and 20. The upper disk wall 15 is provided with openings 21 to permit the outflow of gas from the pasasges 13. The lower disk wall 16 is provided with apertures or openings 22 to allow the inflow of gas into the chambers or passages 13. A tube 23 having a passage 24. is brazed or otherwise integrally connected at 25 to the top 8 of the casing 5, and this top has a tubular extension 26, which is aXially alined with the tube 23 a d its upper end receives a suitable burner tip 27. The top 8 has a filling opening 28, and pivoted to the top, as shown at 29 is a semi-circular closure 30 for covering the filling opening 28. The end portion of the closure 30 (which is constructed of sheet metal) is provided with a depression 31 formedupwardly therein, and which depression is designed to receive the bulge 32, which is formed by bulging a portion of the top 8 to hold the closure in a position covering the'opening. The lower end of the tube 23 merges into the circular portion 33, which is provided with a flange 34, which fits over I and is brazed or otherwise suitably connected to thecasing 12; A tube 35 is threaded to the annular flange 10, as shown, and its upper end merges into a circular portion 36, which has an annular flange 37, which is brazed or otherwise suitably connected on to the lower end of the casing 12. The combined passages 13 constitute storage means auxiliary to thecarbid receptacle and into which the gas collects to insure a substantially even fiow through the passage Qtto the burner 27, and by such. even flow, fiuttering'of the lightis substantially eliminated. The bot tom 6 is provided with a tapering opening 38, the wall of which constitutes a valve seat 39 for theneedle valve 40 of the rod &1, the upper end portion of whichis threaded at 4:2 in the top 8, and is provided with a knurled head 43, whereby the rod maybe adjusted. The interior of the tubular cass ing 5 is designed to contain water, andby opening the needle valve, a gradualifiow,'or rather a drop by drop fiowis allowed to pass into the carb-id receptacle, ,and thoroughly saturate'the felt pad 44 (which is located on the top of the'carbid) and the moisture from the pad so acts on the carbid as to generate gas, which filters through the pad and through the passage of theftube 35,. then through the openings or apertures22, and collects 1n the passages 13, and owing to these passages being surrounded by the water, the gas is cooled, which together with the said passages'13 (which insure an even flow of gas to the burner) substantially eliminates fluttering of the light at the burner.

Theinvention having been set forth, what is claimed as new and useful is In a carbid lamp for miners, a carbid receptacle having a tubular casing rising upwardly therefrom and being detachably con nected thereto so as to allow ready access to the carbid receptacle, said tubular casing having a water chamber therein provided with an opening of communication with said receptacle, an auxiliary casing centrally disposed in the tubular casing, the auxiliary casing forming a collection chamber, the lower end of said auxiliary chamber being restricted, the upper end of the auxiliary chamber being restricted and" terminating in a burner,a cap for the upper end of the tubular casing carried by said restricted burner portioma. needle valve disposed in the water chamber between the auxiliary casing and the wall of the tubular casing, the restricted ends of the auxiliary casing being detachably carried by the auxiliary casing, a' flanged bushing screwed into the lower end of the tubular casing and forming a closure for the water chamber, said detachable connections of the restricted ends of the auxiliary casing, the lower end of the tubular casing and the flanged bushing allowing the various parts to be easily and quickly assembled or disassembled for cleaning p ur poses.

In testimony whereof I have signed my name to this Specification in the presence of two subscribing witnesses.
